ZCS Install Passwords? Where can I find them?

I am using the 32bit to 64bit guide and it's telling me when preping the 64bit server, run the installer and use the same passwords as the 32bit server install did. For some of the random generated passwords I have no idea what I used. I know what the admin account password and such is, but that's about it.

Is there a config file I can pull these up in? How would I go forward with this?
